Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452932, here are decompositions:

31 + 31452901 = 31452932
73 + 31452859 = 31452932
103 + 31452829 = 31452932
139 + 31452793 = 31452932
163 + 31452769 = 31452932
193 + 31452739 = 31452932
211 + 31452721 = 31452932
283 + 31452649 = 31452932

Showing the first eight; more decompositions exist.
